E. SCHALL Dec. 28, 1954 APPARATUS FOR REHOVABLY MOUNTING LIPSTICKS ORTHE LIKE Filed Dec. 7. 1951 United States Patent APPARATUS FOR REMOVABLYMOUNTING LIPSTICKS OR THE LIKE Egon Schall, New York, N. Y., assignor toLever Brothers Company, New York, N. Y., a corporation of Maine Thepresent invention relates to means for mounting a lipstick, or the like,in a casing.

In known dispensers of the above type removal of a lipstick from thedispenser casing is difficult without soiling the fingers. Similarly itis ditficult in known dispensers to exchange the lipstick if it isdesired to do so.

One of the objects of the present invention is to provide a means forremovably mounting a stick of material to be dispensed in a dispensercasing so that it will be possible to replace one stick of material inthe casing with another stick of a dilferent type of material, and inthis way the same casing may be used for the different types of materialto be dispensed.

Another object of the present invention is to provide a removablemounting of the above type which is of an exceedingly simpleconstruction so that one type of material to be dispensed may bereplaced by another type with a minimum of effort.

A further object of the present invention is to provide a removablemounting of the above type which is of a sturdy construction so that thesame will be usable over a long period of time.

Yet another object of the present invention is to provide a removablemounting of the above type with a safety means to prevent damagingthereof.

An additional object of the present invention is to provide a means forcovering the material removed from the casing.

With the above objects in view the present invention mainly consists ofan apparatus for removably mounting, in a dispenser casing, a stick ofmaterial to be dispensed, this apparatus comprising a support member tobe mounted in the casing for movement along a predetermined axis. Acarrier is also mounted in the casing to carry a stick of the materialto be dispensed, and a tubular member is associated with the carrier tobe located about the material to be dispensed so as to at leastpartially cover the same. A first connecting means is mounted on thecarrier and one of the support or tubular members for detachablyconnecting this one member to the carrier by rotation with respectthereto, and a second connecting means is mounted on the carrier and theother of said support and tubular members for detachably conmeeting thisother member to the carrier by translational movement with respectthereto.

The novel features which are considered as characteristic for theinvention are set forth in particular in the appended claims. Theinvention itself, however, both as to its construction and its method ofoperation, together with additional objects and advantages thereof, willbe best understood from the following description of specificembodiments when read in connection with the accompanying drawings, inwhich:

Fig. l is a sectional, partly fragmentary view of one possible apparatusfor carrying out the present invention;

Fig. 2 is an exploded view of associated parts of the apparatusillustrated in Fig. 1;

Fig. 3 is an exploded view of a dilferent embodnnent of the partsillustrated in Fig. 2;

Fig. 4 is an exploded view of another embodiment of the parts shown inFig. 2; and

Fig. 5 is an exploded view of still another embodiment of the partsillustrated in Fig. 2.

Referring now to the drawings, there is shown in F g. 1 a casing havinga tubular base member 11 provided with a closed bottom, this closedbottom having a flange 12 which may be knurled so that tube 11 may beheld 2,698,085 Patented Dec. 28, 1954 ice non-rotatably by the user. Thetubular base member 11 is formed with at least one elongated slot 13.

Loosely located about tubular member 11 and resting on the shoulder 14thereof isa cylindrical member 15 having an upper end locatedimmediately below a shoulder 16 formed in the upper end portion oftubular member 11. This cylindrical member 15 is formed with a helicalslot 17 extending from one end thereof to the other end thereof.

A tube 18 is located about the cylindrical member 15, this tube 18making a fairly tight frictional contact with the member 15 so as topress the same inwardly toward the tube 11 while permitting freerotation of members 15 and 18 with respect to tube 11. The inward movement of tube 15 causes the top end thereof to be located immediatelybelow shoulder 16 so that members 15 and 18 cannot be removed from tube11 except by forcibly sliding member 18 01f member 15. The tube 18 isprovided at its upper end with an inwardly extending flange to improvethe appearance of the casing 10.

A pin 19 extends through the slot 13 and has a head 20 located in thehelical groove 17 of cylindrical member 15, this head being wider thanslot 13 so that pin 19 cannot fall through this slot. The tube 18 holdsthe head 20 in the helical groove 17.

A cover member 21 is provided to cover the entire casing, this covermember 21 being adapted to frictionally engage the side portion 22 ofthe tubular base member 11 so as to be easily removable therefrom. Ifdesired the outer surface of cover member 21 may be knurled.

Mounted for movement along a predetermined axis within the tube 11 is asupport member 23 which is hollow, internally threaded adjacent theupper open end thereof and formed with a side aperture 24 through whichpin 19 extends. It is thus apparent that upon rotation of tube 11 withrespect to tube 18, the cylindrical member 15 remaining stationary withthe tube 18, the support member 23 will move up or down in the tube 11due to the movement of head 20 of pin 19 in the helical slot 17 ofcylindrical member 15. Thus support member 23 is shown in an enlargedscale in Fig. 2.

A carrier 25 is threaded adjacent its lower end so as to be detachablyconnected to the threads of support member 23, this carrier beingadapted to carry a stick of material to be dispensed, such as, forexample, the lipstick 26, shown in dot dash lines in Fig. 1. Thiscarrier 25 may be hollow to suitably support the stick 26 and isslightly conical at its upper side surface, as is shown on anexaggerated scale in Fig. 2. The carrier 25 is provided on or adjacentthe conical side surface portion thereof with at least one projection27, four of these projections 27 being used in the particular embodimentillustrated in the drawings. As is apparent from Figs. 1 and 2 theprojections 27 have an upper substantially semicircular edge.

A tubular member 28, which may be closed at the upper end thereof, isadapted to be located about the stick 26. This tube 28 is provided atits lower end with inwardly extending recesses 29 which aresubstantially semi-circular so as to matingly engage with theprojections 27, and the lower end portion of tube 28 is slightlyconical, as shown in exaggerated scale in Fig. 2 so as to frictionallyengage the upper slightly conical side portion of carrier 25.

The operation of the above described structure is believed to beevident. When it is desired to use the stick 26, the cover 21 is removedfrom the casing 10 and the members 18 and 11 are turned with respect toeach other so as to move the support member 23 upwardly to the top ofthe casing 10. The tube 28 is then slipped off from the carrier 25,which is threadedly connected to support member 23, as shown in Fig. 1,so as to expose the stick 26. Then the tube 28 is replaced about thestick 26 and on the carrier 25, the members 18 and 11 are rotated withrespect to each other to move support member 23 to the bottom of tube11, and the cover 21 is replaced. In Fig. 2 the tube 28 is shown out ofline with the pro ections 27 to illustrate that the tube 28 may simplybe slipped onto the carrier 25 so that the lower end of tube 28 engagesthe top edge portions of projections 27. It is then only necessary toturn the'tube 28 slightlyso-that it may be further moved onto carrier 25and have the recesses 29 aligned with projections 27 in a very simplemanner. The tube 28 remains connected to the carrier 25 by frictionalcontact therewith.

If it is desired to replace stick 26 by another type of stick, thesupport member 23 is again raised to the top of the casing 10, in themanner described above, after cover 21 has been removed. The tube 28 isthen turned, instead of being removed from the carrier 25, and becauseof the engagement of projections 27 withrecesses 29, the carrier 25turns with the tube 28 so as to be unscrewed from the support member 23.After carrier 25 is removed from support 23, it remains connected totube 28 by the frictional engagement between these members 28 and 25.Then another assembly of elements 28 and 25 carrying a different type ofstick 26 is threaded into the support member 23 so that the same casingand cover 21 are usable with this othertype of stick 26.

It will be noted that when an assembly of elements 28 and 25 isconnected to the support 23, the tube 23 is turned so as to also turnthe carrier 25 frictionally connected thereto and thread the carrier 25onto the support 23. When all of the threads on the carrier 25 haveengaged the threads of supports 23, continued turning of the tube 28will only result in slidable movement of recesses 29 over projections 27so that, in this way, the threads on members 23 and 25 are protected andtoo tight an engagement between these threads is prevented.

As is shown in Fig. 3, the support member 23' may be provided withrecesses 29' and with an inner conical upper surface so as to engageprojections 27' on carrier 25' and the lower conical side surfaceportion of the latter, the tube 28' then being threadedly connected tothe carrier 25. This construction is capable of producing thesameresults as the construction shown in Figs. 1 and 2, the only differencebeing that carrier 25' is detachable from support member 23' bytranslational movement Withrespect thereto and the tube 28 is detachablefrom carrier 25' by rotation with respect thereto.

As is apparent from the above description, the essence of the inventionresides in making one of the members 23 or 28 detachable from member 25by such a movement which does not detach the other of the members 23 or28 from the carrier 25 and, vice-versa, to make the other of the members23 or 28-detachable from member 25 by a movement of such type which doesnot detach the first-mentioned of the members 23 or 28.

In Fig. 4 there is illustrated a further embodiment of the inventionwhich is the same as that shown in Fig. 2 except that the carrier 25 isformed with a bayonet slot 30 which engages a pin 31 fixedly mountedwithin the support 23" to render carrier 25" detachable from support23"by rotation with respect thereto.

In the specification and the claims which follow all references tothreaded connections are intended to include both threaded connections,shown in Figs. 1, 2 and 3, and a bayonetslot and pin connectiomshown inFig. 4.

In Fig. 4 a further embodiment is shown in which the support member 23is hollow and internally-threaded in the same manner as in theembodiment shown in Figs. 1 and 2. The tubular case member indicated inthis embodiment with reference numeral 32 is provided with twooppositely directed screw threadings 33 and 34 spaced from each other byshoulder 35. The lipstick cover 36 is provided with a screw threading 37meshing with the screw threading 34.

It is evident that a device of the above type operates in the samemanner as the removable lipstick mounting shown in Figs. 1 and 2.

In order to secure the lipstick to the support 23 the same is insertedin the tubular case member 32 and the cover 36 screwed thereon. Then thethus-assembled unit is screwed into the internally screw-threadedsupport 23 until shoulder 35 abuts against the upper edge of thesupport. This prevents further turning of'the tubular case memberrelative to the support and further turning of the cover 36 will resultin detachment of the cover from the tubular case member 32.

If it is desired to remove the case member 32it is'only necessary toscrew the cover 36 on screw-threading 34 of the case member 32 and turnit continuously into the opposite direction until the cover abutsagainst the shoulder 35; further turning 'ofthe"cover'will detach thecase ingember 32 together with the cover from the support Although theabove description refers specifically only to a lipstick, it is to beunderstood that the present invention is applicable to any stick ofmaterial to be dispensed.

It will be understood that each of the elements described above, or twoor more together, may also find a useful application in other types ofapparatus for removably mounting a stick of material to be dispensed ina casing differing from the types described above.

While the invention has been illustrated and described as embodied in anapparatus for removably mounting a lipstick in a casing, it is notintended to be limited to the details shown, since various modificationsand structural changes may be made without departing in any way from thespirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist ofthe present invention that others can by applying current knowledgereadily adapt it for various applications without omitting featuresthat, from the standpoint of prior art, fairly constitute essentialcharacteristics of the generic or specific aspects of this inventionand, therefore, such adaptations should and are intended to becomprehended within the meaning and range of equivalence of thefollowing claims.
